Objective: The aim of the study was to assess the influence of overweight and obesity in youth on adipocytokines levels, inflammatory and oxidative markers.
Design and methods: Cross-sectional study of 149 young adults (54 normal weight, 27 overweight, 68 obese). Clinical and biochemical parameters, including lipid profile, fasting glucose, insulin and HOMA were determined. The levels of adipocytokines(adiponectin, retinol-binding protein 4 (RBP4), and resistin), markers of inflammation (high-sensitivity C-reactive protein (hs-CRP) adenosine deaminase (ADA), dipeptidyl peptidase-IV (DPP-IV) activities, serum IL-6 levels and oxidative stress (malondialdehyde and ferric reducing antioxidant power - FRAP) were measured.
Results: Obese subjects presented significantly lower levels of Sulfhydryl groups (SH groups), adiponectin, HDL-C and the highest levels of RBP4, hs-CRP, resistin, IL-6, ADA, DPP-IV activities, and oxidative markers than compared to those who were of normal weight. There was a positive correlation between hs-CRP, IL-6, DDP-IV activity, anthropometric measurements and biochemical parameters.
Conclusions: This analysis shows that resistin, RBP4, IL-6, ADA and DPP-IV activities and the reduction of adiponectin can promote inflammation, impairment of insulin sensitivity, and may contribute development of the pathways involved in obesity. These findings may hold promise in identifying new inflammatory markers, benchmarks that assist in the diagnosis and monitoring of patients with overweight and obese.
